Dermatology
Mohs stages. Cosmetic-vs-medical splits. Pathology modifiers nobody on staff fully knows.
Dermatology billing has more surface-area for error than most specialties — Mohs stages, excisions with variable margins, pathology splits, cosmetic versus medical revenue. We specialize in all of it.
Who this serves: Independent dermatology practices, Mohs-heavy practices, and dermatology departments with practice-like P&Ls.
Dermatology has two overlapping revenue streams — medical and cosmetic — that need to stay cleanly separated for regulatory, tax, and operational reasons. Most practices treat this as the practice manager's problem. It ends up being fifteen hours a week of manual reconciliation.
Mohs is the other compounding issue. The Mohs procedure generates multiple coding layers: the surgical removal (17311–17315, depending on stages and site), the pathology (88305 or 88307), and often repair coding. Each piece can be mis-coded independently. Together they're the highest-value, highest-denial category in most dermatology practices.
We've lived inside dermatology billing long enough to know exactly where the leaks are.
What separates a specialty-fluent biller from a generalist.
